Abstract
A serial link data monitoring apparatus for targeting a given Bit Error Rate (BER) for stable serial link data communication is disclosed. An interface unit may be configured to receive data via a serial interface, and circuitry may be configured to monitor errors in the data. The circuitry may be further configured to perform one or more first training operations in response to a determination that the number of errors detected in the data is greater than a first threshold value, and perform a second training operation in response to a determination that a number of first training operations performed in a predetermined period of time is greater than a second threshold value. An amount of time to perform the second training operation may be greater than an amount of time to perform a given one of the first training operations.
